Stillwell-Hansen

What Stillwell-Hansen does

Stillwell-Hansen is a privately held manufacturers' representative and value-added technical services firm headquartered in Edison, New Jersey, founded in 1969. Operating from a 26,000 square foot facility in Raritan Center since 1992, the firm holds exclusive rights as the only authorized Vertiv sales and service representative across 12 northern New Jersey counties, functioning as an extension of its manufacturing partners rather than as an independent product company. Leadership has remained within the founding Stillwell family: Carol Stillwell, who joined as a secretary in 1969, has served as President and CEO since 1996 following Paul Hansen's retirement, with Glenn Pabst as Vice President.

The company's portfolio centers on the Vertiv critical infrastructure stack: Liebert uninterruptible power supplies (including lithium-ion variants), power distribution units, racks and enclosures, Liebert iCOM thermal management, Liebert XDU coolant distribution units for liquid cooling (operating from -20°C to +70°C), and the SmartMod, SmartMod Max, SmartMod Combo, and MegaMod lines of prefabricated modular data centers. Complementing Vertiv are Condair humidification and dehumidification systems, Systecon modular central utility plants with Wire-to-Water Efficiency optimization (a methodology developed in 1984), fire detection and suppression from Kidde, Fike, and VESDA by Xtralis, and Systecon NIMBUS fluid cooling for industrial and healthcare retrofits. Vertical coverage spans data centers, healthcare facilities, government, manufacturing, commercial buildings, growhouses, indoor pools, pharmaceutical, and printing applications.

Stillwell-Hansen generates revenue through two streams: manufacturer commissions on equipment sales across its 7 divisions (HVAC Sales, SH Datasite Protection, SH Technical Services, SH Technical Parts, IT Solutions, SH Technical Safety & Compliance Solutions, and Liebert/Emerson Sales), and service revenue from a dedicated technical service department performing startup, troubleshooting, and repair work, supported by a multi-million dollar parts inventory. Go-to-market is direct field sales led by technically proficient staff averaging 25+ years of experience, targeting enterprise customers across its exclusive northern New Jersey territory. The firm is privately held with no external capital, no M&A activity, no app or API surface, and no disclosed financials.
